Hybrid tea rose plant name `Macchopsu`

ABSTRACT

A hybrid tea rose variety producing red flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid tea rose variety which was originated by my crossing as seed parent the variety known as `Louise Gardner` and as pollen parent the variety known as `Mme. Delbard`, U.S. Plant Pat. No. 4,391. The varietal denomination of this new rose is `Macchopsu`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive red flowers borne on a bushy, vigorous plant.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction for roses may be also employed.

Comparison with Parents

`Macchopsu` has an orange cast whereas `Mme Delbard` is a true scarlet red. In addition, `Macchopsu` is a much freer blooming plant than `Mme Delbard`. `Louise Gardner` is a yellow blend, small-flowered hybrid tea producing flowers in small trusses while `Macchopsu` produces flowers more singly and whereas `Macchopsu` has glossy green foliage, `Louise Gardner` has matte grey-green foliage.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY
